Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Update astro/geographiclib to 1.4.9
Highlights:
- Update from 1.4.6 to 1.4.9
- MAGNETIC_EMM2017 model addd
- Switched to CMake for build
head/tail usage must be patched to avoid use of --lines; work is in progress
to eventually grow this long-option alternative to -n so that such patching
isn't necessary at some point in the future.

Bump PORTREVISIONs for ports depending on the canonical version of GCC and
lang/gcc which have moved from GCC 4.9.4 to GCC 5.4 (at least under some
circumstances such as versions of FreeBSD or platforms).
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using using Mk/bsd.octave.mk which in turn has USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c++11-lib, c++14-lang,

Add new port astro/geographic lib
PR: 187280
Submitted by: Tatsuki Makino
GeographicLib is a small set of C++ classes for performing conversions
between geographic, UTM, UPS, MGRS, geocentric, and local cartesian
coordinates, for gravity (e.g., EGM2008), geoid height, and geomagnetic
field (e.g., WMM2010) calculations, and for solving geodesic problems.
The library may be used from .NET applications using the NETGeographicLib
wrapper library. It is a suitable replacement for the core functionality
provided by geotrans.
